|JBL 6020 Amplifier|
|Category:||Audio Video TV Multimedia|
The JBL 6020 is a highly reliable, conservatively rated amplifier, designed for professional sound engineering applications where a high degree of performance is required. The circuitry has been carefully designed to reduce the possibility of failure within the specified environmental and electrical conditions. A protective circuit is utilized in this Amplifier which makes it virtually impossible to damage it under any conditions of overload, including shorted or grossly mismatched load, inductive load at low frequencies, capacitive load at high frequencies, excessive input signal, white noise or installation errors. The JBL 6020 can be overdriven by at least ten times normal input voltage, from 40 Hz to 15 kHz, and eventually produces square waves increasing in RMS value up to about 250 Watts at which point the output actually begins to decrease. The DC fuse is intended as a protective device for the power supply in the event of output stage malfunction. In the event of fan failure, the thermal switch will activate if the heat sink temperature exceeds 200°F. The 6020 Amplifier is designed for maximum flexibility in varying input and output arrangements. A standard unbalanced 50,000-ohm input is provided which can be converted to balanced line bridging or matching with the installation of the accessory 5195 transformer. A 250-Hz low cut filter switch reduces the possibility of damaging horns. All the power outputs are balanced and the bridging output is unbalanced. For studio applications, broader bandwidth and reduced distortion levels can be achieved with slight modification of the circuitry. Bypassing the output transformer results in a 200-Watt output at less than 0.5% total harmonic distortion, 30 to 12,000 Hz (±0.5 dB) operating into a 4-ohm load. The excellent engineering of this unit is accompanied by an equally excellent layout with serviceability in mind at all times. All Components are accessible and easily replaced with particular emphasis on output and driver device removal and installation.
